Description of the invention (1) [Technical field of the invention] The present invention relates to plastic products such as plastic chess cars, etc. In particular, it relates to a method for forming products with undercut parts by vacuum forming [Previous Technology] The forming method and vacuum forming method will be described below, and the length of the punch on the metal chess of the heater will be used. Afterwards, it is true that the shaped products such as the yoke and the like have undercut methods for the lower metal. The vacuum of plastic molded products such as conventional model cars leaving the mold is made of thermoplastic resin to form the resin sheet. It is simpler to absorb in the above vacuum forming in the softened and empty state, but it is more difficult to mold the product The mold is divided into a plurality of resin thinned into a softened resin thin metal chessboard. For example, the chess pattern is separated from the cast mold, and the piece is fixed to the state, and then the piece is stretched to be formed into a mold. , So that the upper mold is pushed up and the shape of the bottom choke is pushed up. The underside of the rod without undercut must be thought of. Please read the item on the back to bind The printing mold of the Zhengong Consumer Cooperative of the Central Ministry of Economic Affairs of the Ministry of Economic Affairs is gold, and the side bite of the steam mold is formed to use the known practice table system 3 ΙΒ The part of the block before the chess is assembled before the insurance is guaranteed.

Invention description (2) Slide on the support 2 In the direction of the arrow b, the model car can be easily taken out from the metal mold. Also, Figure 4 shows the other metal molds that are known. This metal mold is composed of: central casting chess 3 a; and in the hood and rear window. Part * is composed of a front split die 3 b and a rear split die 3 c divided along a slanting line that decreases gradually upwards. Also, after vacuum forming, the central type 3 a is formed by a cylinder arranged below the support 2 4 to make it fall in the direction of arrow a * and then slide the front and rear split molds 3 b, 3 c in the direction of arrow b, by which the chess car can be separated from the metal mold. [Problems to be Solved by the Invention] However, the conventional gold-layer mold of FIG. 3 described above is for a model car having an undercut portion 1 a > indicated by an imaginary line above the rear bumper of the model car, There may be a problem that it cannot be divided into post-splicing modes 1 c. In addition, for the lower gold layer mold of the above-mentioned conventional 4th model, although a model car with undercut 1 a / can be produced, but because the central mold 3 a must be lowered, it is not only the structure of Jinqiqi It will become more complicated, and at the same time, there will be a problem that it is necessary to use a large-scale molding machine in order to lower the central mold 3a by a considerable amount.

In addition, the division between the center chess and the front and rear split molds is provided with an auxiliary plate that is installed according to a cutting line at a different angle from the oblique line. , And when the central chess rises, it is ideal to make the front and rear split dies slide to the cutting line of the above auxiliary plate. [Embodiment of the invention] Hereinafter, the plastic products (models for implementing the present invention will be explained according to the first 圔The metal mold of the automobile) forming method. The metal mold of the present invention consists of: a central mold 5 a; and this paper scale is used in China National Standards (CNS) A4 specification ϋ〇Χ297 mm j ~ " ~ 6 -(Please read the precautions on the back and then ^ write this page).

Description of the invention (4) In the section of the engine director and the rear window, along It is composed of a front piece 5 b and a back piece 5 c divided by an oblique line L which gradually expands upward. Moreover, after vacuum forming, the central chess 5a is raised by the gas red (not shown) arranged on the back of the support 2, and then the central mold 5a is raised, and the front and rear pieces 5b are pushed together, 5 c can slide in the center direction. Next, the forming method of using the above metal chess to make a model car will be explained. Similar to the conventional vacuum forming method, the resin sheet after heating and softening is lowered to the metal mold, and then stretched to After the length of 預鑄, the air is drawn through the through hole of the metal chess to perform vacuum forming casting. Then, the softened plastic sheet is adhered to the entire circumference of the metal mold, and after solidification, the central chess 5 a rises in the direction of arrow a, while sliding the front and rear split dies 5b, 5c in the direction of arrow b at the same time, so that the front and rear split dies 5b, 5c can be separated and cast when passing the undercut of the chess car 1 operation. In addition, when the center mold 5 a rises, although a small amount of expansion thrust acts on the undercut of the model car 1, the model car is made of plastic sheet, so it has considerable elasticity | so it will not damage the soil. The undercut part of the model car * In the above-mentioned gold-tread mold, when the central chess 5 a moves up and down, the central mold 5 a and the front and rear split molds 5 b, 5 c slide along the diagonal line L, so aluminum is generally used Metal molds will cause wear on sliding surfaces due to long-term repeated use.

Description of the invention (5) Here, as shown in circle 2, this embodiment fixes the auxiliary plate 6 with abrasion resistance to the center mold 5a and the front split mold 5 the lower side of the sliding joint between b, and the lower side of the sliding joint between the central mold 5 a and the rear split mold 5 c, and changing the angle with the diagonal line L, that is, forming a diagonal line L The steep section line 1 · In this way, by forming the auxiliary plate 6 on a part of the sliding surface, not only will it come into contact with the diagonal line L between the center mold 5 a and the front and rear split molds 5 b, 5 c during forming, It will also come into contact with the cutting line 1 of the auxiliary plate 6 [Fig. 2 (a)]. Then, after the forming is completed, the central mold 5a is raised in order to separate the yong chess, and when the front and rear split pieces 5b, 5c slide, the front and back pieces The molds 5b, 5c are only slidingly connected to a part of the cutting line 1 of the auxiliary plate 6, so that the part of the oblique line L can be separated * Therefore , The sliding time between the central mold 5 a and the front and rear split molds 5 b, 5 c is extremely short, and the relative wear between the two is almost non-existent, which promotes the improvement of the service life of the metal mold. L is formed in the space part where the wheel will be cut after the finished product, so the auxiliary plate 6 is fixed in the space where the wheel is cut afterwards. Therefore, even after the finished product, it protrudes from the outer peripheral surface. It is cut off, so there is no inconsistency. [Effect of the invention] The present invention is divided into a central mold and a front and rear split mold with a diagonal line L as described above, while raising the central mold while simultaneously Make the size of the front and back spelling paper apply to the Chinese National Standard (CNS) A4 specification (210X297mm) (please read the precautions on the back before writing this page).
