Ein Formeinsatz (1) für eine Spritzgießform mit einem Formbereich (4) zur Bildung eines Bürstenteilkörpers (21) und mit sich in den Formbereich (4) erstreckenden Aufnahmelöchern für Borstenbündel (7) ist mehrteilig ausgebildet. Der Formeinsatz (1) weist dabei ein erstes Formeinsatz-Teil (2) mit dem Formbereich (4) für den Bürstenteilkörper (21) und mit Teil-Aufnahmelöchern (5) zur bereichsweisen Aufnahme von Borstenbündeln (7) sowie ein zweites Formeinsatz-Teil (3) mit sich in Gebrauchslage an die Teil-Aufnahmelöcher (5) des ersten Formeinsatz-Teils (2) anschließenden Teil-Aufnahmelöchern (6) auf (Figur 3).
技术问题语段：
The technical problem addressed in this patent is the high cost and complexity of producing mold inserts for injection molding brushes. The invention proposes a solution by designing the mold insert in two parts, with the first part having the mold area and part-receiving holes for bristle bundles, and the second part having adjoining part-receiving holes. This reduces the demands on quality and dimensional accuracy only in the mold area, and allows for simpler and less expensive methods of production. The two parts can be aligned with each other using adjustment pins and recesses, and then fixed together using plastic or metal.
技术功效语段：
The patent text describes a mold insert for injection molding brushes that can be produced in a simple and cost-effective way. The mold insert is designed in two parts that can be easily aligned and fixed together. The first part is made with a wire cutting process and is the more expensive part. The second part is made of plastic or metal and can be produced using less complex methods. The mold insert can be used to produce different brushes with different properties by simply changing the pattern of the bristle field. This reduces the cost of the entire mold insert. The mold insert is designed to be easily aligned and fixed with the second part, which is made of plastic or metal. The two parts can be connected using adjustment pins or adjustment sleeves. The invention simplifies the production process and reduces costs for multiple brushes.
权利要求：
1. Mould insert (1) for an injection mould, comprising a moulding region (4) for forming a brush part body (21) and having receiving holes, which extend into the moulding region (4), for bristle bundles (7), wherein the mould insert (1) is configured in multiple parts and includes a first mould insert part (2) having the moulding region (4) for the brush part body (21) and having partial receiving holes (5) for receiving bristle bundles (7) in regions, and a second mould insert part (3) having partial receiving holes (6) which, in a use position, adjoin the partial receiving holes (5) of the first mould insert part (2), characterised in that adjustment pins (14) are provided on the second mould insert part (3), which engage into recesses (15) of the first mould insert part (2) and can be fixed in the recesses (15), wherein the adjustment pins (14) consist of plastics material and can be connected to the recesses (15) of the first mould insert part (2) by incipient melting or wherein adjustment bushes (16) for axially fixing the adjustment pins (14) in the recesses (15) are provided and wherein in each case a gap which can be filled with a filling composition is provided between the inner wall of the recess (15) and the adjustment bush (16).
2. Mould insert as claimed in claim 1, characterised in that the second mould insert part (3) consists of plastics material.
3. Mould insert as claimed in claim 1 or 2, characterised in that the filling composition is a tie resin.
4. Mould insert as claimed in any one of claims 1 to 3, characterised in that the first mould insert part (2) can be fixed to the second mould insert part (3) by means of a screw connection.
5. Mould insert as claimed in any one of claims 1 to 4, characterised in that the mould insert (1) is insertable into a cassette (12) which has a plurality of recesses for receiving in each case a mould insert (1) and which forms a mould insert carrier.
6. Mould insert as claimed in claim 5, characterised in that the first mould insert part (2) is releasably connectable to the cassette (12) by a screw connection.
7. Mould insert as claimed in any one of claims 1 to 6, characterised in that the moulding region (4) for the brush part body (21) of the first mould insert part (2) is configured to receive a bristle carrier plate (20).
8. Mould insert as claimed in any one of claims 1 to 7, characterised in that the partial receiving holes (5) of the first mould insert part (2) in each case have a bevel (11) on an end thereof which faces towards the second mould insert part (3).
9. Mould insert as claimed in claim 8, characterised in that the bevel (11) of a partial receiving hole (5) of the first mould insert part (2), with respect to the main direction of extent of the partial receiving hole (5), is larger than the remaining portion of the partial receiving hole (5).
10. Mould insert as claimed in any one of claims 1 to 9, characterised in that individual ones or all of the partial receiving holes (5) of the first mould insert part (2) are arranged obliquely.
11. Mould insert as claimed in any one of claims 1 to 10, characterised in that individual ones or all of the partial receiving holes (5) of the second mould insert part (3), at least in the region facing towards the first mould insert part (2), are arranged to extend in an oblique manner.
12. Mould insert as claimed in any one of claims 1 to 11, characterised in that individual ones or all of the partial receiving holes (6) of the second mould insert part (3), at least in portions, have an angled or curved profile and the partial receiving holes (6), in an introduction region which faces away from the first mould insert part (2), are arranged in each case perpendicularly to the surface of the second mould insert part (3).
